Here's a link for nationwide and state-by-state percentage spread in prices between gas and E85:
http://e85prices.com/
Nationwide, there's an overall 12% difference right now. A few states have as much as a 16% difference and some (AZ, UT), show E85 is more expensive than gas.
I'll save my
opinions about E85 for another forum section...
